The turbine exhaust, low pressure steam is used for process heating. Combustion of black liquor in the recovery boiler furnace needs to be controlled carefully. High concentration of sulfur requires optimum process conditions to avoid production of sulfur dioxide and reduced sulfur gas emissions.
The result of analyses indicates that the emission rates for steam boilers were ranging from 0.0083 kg NOx/hour to as high as 0.2771 kg NOx/hour while the total emission load was 1.9969 kg NOx/hour.
Noninteractive gases such as nitrogen, argon and oxygen carry over almost entirely with the steam, having no relationship to moisture carryover. Excessive steam impurity concentrations can also be caused by feedwater and boiler water chemistries that favor volatile species formation.

provide steam and/or hot water. Commercial boiler systems are used for heating with hot water or steam in commercial buildings. Commercial boilers are generally small in size compared to industrial boilers. A commercial boiler is typically defined by its common function – a boiler
Flue gas in steam boiler contains emissions which can not be acceptable for environment and health. They are nitrogen oxide (NOx) and sulfur oxide (SOx). Nitrogen oxide is formed when combustion process burn certain fuels (coal, gas, and oil) at high temperature.
water-tube boilers, tubes containing water are heated by combustion gases that flow outside the tubes, while in the fire-tube boilers hot combustion gases flow inside the tubes and water flows outside. Key design parameters to determine the boiler size and power are the output steam mass flow rate, pressure and temperature.
Dec 29, 2014 · Existing coal-fired boilers with a heat input equal or greater than 10 million Btuh are required to adhere to emission limits for mercury and carbon monoxide. This new regulation determines what a boiler’s emissions are and how often the boiler must be tuned up, based on its size and type.
